I am aware that many minor changes may be made in the construction and arrangement of the several parts of my device without in the least departing from the nature and principle of my invention.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a side bearing for railway-cars, the combination with burden-carrying balls, of antifriction devices under said balls for supporting the same, said antifriction devices being arranged to the side of the vertical axes of said balls, and a support having recesses in which recesses are located said antifriction devices; substantially as described.

2. In a side bearing for railway-cars, the combination with a casting having recesses, of antifriction devices arranged around the side walls of said recesses, and burden-carrying devices supported by said antifriction devices; substantially as described.

3. In a side bearing for railway-cars, the combination with a support having recesses, said recesses having undercut stalls in their side walls, antifriction devices in said stalls, and burden-carrying balls; substantially as described.

at. In a side bearing for railway-cars, the combination with a casting having marginal flanges, of antifriction devices submerged in a lubricant, burden-carrying balls supported at difierent points by said antifriction devices, and means for holding said balls in position; substantially as described.

In testimony whereof I hereunto set my hand, in the presence of two witnesses, this 31st day of January, 1902.

CHARLES H. WILLIAMS, .IR.
